boys names, what do you think?

We have finally chose Leo, if we have a boy but we are unsure about middle name, would either be...Leo Anthony MillerorLeo David MillerAnthony being my oh's name, my dads name, my oh's dads middle name and my nephews name. And David being my oh's middle name and both of his grandads name, one of which passed away last sept. What do you think?
